Lindsay Lohan's ex, Samantha Ronson, has gotten into some alcohol-fueled trouble of her own.

The 33 year-old DJ was leaving a gig in Las Vegas when she was stopped by police just outside of Baker, California for speeding. Police then gave Ronson a sobriety test, which she failed. She was arrested on two misdemeanor charges of driving under the influence, according to officers quoted by US Weekly.

Ronson was pulled over for going 89 mph in a 70 mph zone in her Porsche.
